Patent number: 10397592Abstract: A method and an apparatus for performing multi-threaded video decoding are disclosed. The method takes use of a multi-threaded scheme to process an encoded picture stream on a picture by picture basis. In the method, multiple threads are used for performing video decoding at the same time, such as one thread for the operation of parsing input bits into syntax elements of one picture implemented by the first thread, another thread for the operation of decoding the parsed syntax elements of another picture into pixel values implemented by the second thread, and the other threads for the operations of the non-reference picture, such as bidirectional predictive picture, including parsing input bits into syntax elements and the subsequent operation of decoding the parsed syntax elements into pixel values. Therefore, the decoding speed is substantially increased, and the decoding efficiency is enhanced.Type: GrantFiled: December 4, 2017Date of Patent: August 27, 2019Assignee: COREL SOFTWARE LLCInventors: Ioannis Katsavounidis, Yu-Nien Chien, Chun-Huan Chuang, Chung-Tao Chu, Te-Chien Chen

Patent number: 9092119Abstract: Computer software applications presently allow the User to preview the impact of some commands on active documents via a small preview window. However, such preview windows are not representative of how the command will impact the entire document. The invention provides a method and system of efficiently and effectively previewing the impact of User commands on the entire document by executing User commands as they are identified. Leaving the menu open, the User is able to identify successive commands until the desired result is reached. Embodiments are described for execution of general commands, text editing commands, relocations of margins or guidelines, and relocations of graphic objects.Type: GrantFiled: October 14, 2010Date of Patent: July 28, 2015Assignee: COREL SOFTWARE LLCInventors: Kevin Unbedacht, Bruce Woodward, Eric Johnson

Patent number: 8837854Abstract: An image processing method for boundary resolution enhancement is disclosed. Firstly, an image is transferred into an image layer. Noise of the image layer is removed by a bilateral filter and crisp edges are retained at the same time. Moreover, the image layer is interpolated by an interpolation filter for resolution enhancement. The image processing method of the present invention can lower the image blur degree substantially, enhance the image resolution and be widely implemented in all sorts of image/video processing hardware devices.Type: GrantFiled: December 18, 2012Date of Patent: September 16, 2014Assignee: Corel Software, LLCInventors: Lihua Zhu, Haihua Wu, Chung-Tao Chu, Richard Hua
